Horizontal flow dissolved air flotation equipment
Horizontal flow dissolved air flotation equipment

1、 Introduction
As a kind of solid-liquid separation equipment commonly used in sewage treatment industry, the horizontal flow dissolved air floatation machine can effectively remove the suspended solids, grease and rubber substances in sewage, and it is the main equipment for sewage preliminary treatment.
2、 How it works
The air dissolving tank generates the air dissolving water, and the air dissolving water is released to the water to be treated by decompressing through the releaser. The air dissolved in the water is released from the water to form 20-40um micro bubbles. The micro bubbles combine with the suspended solids in the sewage to make the proportion of the suspended solids smaller than the water, and gradually float to the water surface to form scum. There is a scraper system on the water surface to scrape the scum into the sludge tank. Clear water enters the clean water tank through the overflow tank at the lower part.
2、 Scope of application

Paper white water pulp recovery and water reuse; removal of heavy metal ions; separation of oil refining wastewater and oil pollution; removal of impurities in tannery wastewater; removal of chromaticity and impurities in textile printing and dyeing wastewater; solid-liquid separation of sludge and membrane after treatment; sludge concentration, etc.
